cpu/x86/smm: allow SSE instructions in SMM modules
If SSE instructions are enabled in the build assume the SMM
modules are compiled with SSE instructions. As such enable
the SSE instructions in SMM mode by setting up the cr4 register.
In addition, provide a place to save and restore the SSE state
in both the relocation handler and permanent handler.
